This invention relates to a multilayer coating system derived from Titanium dioxide free aqueous coating compositions. The multilayer coating system comprises at least two layers including a layer of base coating which provides good hiding function for substrates and a second layer of clear top coating which provides surface protection functions for the coating system. The base coating composition comprises an opaque (co)polymer having at least one void per (co)polymer particle. The top coating composition comprises a duller (co)polymer chosen from a multi-stage (co)polymer, a single stage crosslinked (co)polymer, and mixtures thereof.
